Your mix of simile and metaphor adds a lot of weight to the heaviness of heartbreak. It is one of those experiences that could make us write stanzas like this until the heart itself mends, which could be never in some cases. I can almost hear you read this, speeding up more and more as you near the end of the poem. Great writing, MBT!

For those of us who experienced heartbreak, you have expressed with haunting elegance that experience. For those possible souls out there who has somehow avoided it, they can now know what to expect should they live that long.
